Specification ofLetters Patent. Patented Jul Application filed January 27, 1909. Serial No. 414,431.

To all whom it may concern:

Be it known that I, CHARLns F. AoKnR- MAN, citizen of the United States, residin at Cleveland, in the county of Cuyahoga an State of Ohio, have invented certain new and useful Improvements in Faucet-Couplings, of which the following is a speci catlon.

My invention relates to a new and orlglnal faucet coupling for small hose or tubes employed in connection with syrlnges, bath sprays and the like, and which is especlally adapted to be used where there is no screw thread to make the desired connection, all substantially as shown and described and particularly pointed out in the claim.

In the accompanying drawings, Flgure 1 shows a side elevation of a faucet and a sectional elevation of the coupling member attached thereto, and Fig. 2 1s a side elevation 'of the coupling member alone.

F represents a common form of faucet as found very generally in connection with wash basins and the like and which in itself represents no present novelty but serves to illustrate the use and relation of coupling G therewith. Said coupling, so-oalled, 1s anew article of manufacture complete in itself, and is adapted as above indlcated to make what may be termeda combined slip and cork connection with and closure upon the faucet. To these ends the said cou ling is fashioned as to shape or contour a out as shown, being approximately conical or conoidal in shape and provided with a solid base portion 2 and a nipple 3 centrally thereon adapted to attach hose 4. From said base to the opposite extremity the exterior taper runs in substantially straight lines with a series of ribs 5 thereon, deepest at said base and tapering to about the middle of the coupling where they run' out, in this instance. These ribs serve the double purpose of giving strength to otherwise rather thin outer or sleeve portion 6 of the coupling and of a grip for the hand in pressing the coupling into place, a rotary movement thereof beinghelpful while the direct pressure is being applied to crowd it into correct engaging position, relatively as seen in Fig. 1. The said sleeve 6 has substantially the same thickness throughout and starts in head 2. Inside thereof and separated therefrom all around by space 7 1s the stopper portion 8 of the coupling.- 'This part or portion is tapered to correspond in the main so that the annular space 7 between sleeve 6 and stopper 8 tapers from the base out in proportions agreeing with both the external and the internal tapers of said parts. Furthermore a fluid passa 'e runs centrally through the coupling an its nipple 3, and in order that said passage may be protected and not contracted when the device is used I provide the same with a tube 9, which extends the full len th thereof internally including nipple 3,n1t in this connection it will be observed that sleeve 6 is of greater length than the stopper and adapted to stretch over the neck of the faucet and engage thereon relatively as shown. This of course implies that sleeve 6 is elastic, as it is, and the entire device partakes of this elasticity more or less, but I prefer to have the base and the stopper 6 harder than the sleeve, and if the stopper was hard or firm enough to enter the faucet and perfectly seal itself therein without compressing or contracting the internal fluid passage objectionably the tube 9 would not be needed. But with the said tube as a precautionary and stiffening part an otherwise flexible and compressible core or stopper 8 can be used and perfect closure of the faucet and effectual engagement of the stopper therein be secured. Compression of the core or stopper also adapts it to different sizes of faucet. Now, it may be further observed in this connection, that the stopper has to hold its place as against the water pressure in the faucet, which sometimes is very heavy, and hence to prevent blowing off of the coupling I find auxiliary means of fastening neces sarv. This is supplied in or by sleeve 6,

which is adapted to be drawn over the faucet more or ess as a given connection may requlre and can even be doubled back u on itself, if necessary, in drawing-the coup mg relatively farther on or into the faucet than shown herein. In any case the sleeve is stretched and thus caused to grip firmly upon the surface of the faucet, and with stopper 8 is found to be suflicient to hold the coupling in place under any city or other local pressure. Cloth reinforcement 10 and wire 11 maybe employed if preferred.

In the manufacture the entire article is molded in one piece and portions thereof may be subsequently treated separately according to the quallty wanted in each.

A head 14 is formed on or about the exy is, 1910.

tremity of the sleeve which is large enough to grip with the thumb and finger to draw the sleeve over the faucet.

If the core or stopper were fairly hard or so as not to compress as shown I should rely upon its taper alone to adapt it to different sizes of faucets. As to the sleeve I may add that while I prefer that it should have proportionate length as shown the matter of length itself is not of first importance but the grip of the sleeve on the faucet to help hold the cork in place.

What I claim 1s:-

A coupling member having a base provided with a nipple 3' at its bottom and a cone shaped core 8 at its top and a passage extending centrally through the same and the extremity of said core tapered to a thin edge, and a flexible substantially cone shaped sleeve about said core and uniformly spaced therefrom the full depth of the core'and extending beyond the extremity thereof approximately one-third the length of said 7 core and having strengthening ribs lengthwise in its base, and a rigid ipe occu ying said passa e and flush at its ends witi the end of said core and of the said nipple respectively, whereb a coupling member is formed which is a apted to various sizes of faucets and adapted to engage u on either smooth or threaded fittings and t e core is pinched between a fitting and the pipe in the coupling.

In testimony whereof I aflix my signature in presence of two witnesses.
